sin, have invented new and useful Improve# f inentsin Cushion-Tires, ofwhich the following'is a. description,4 reference being had vto theaccompanying drawings, which are la part of this specification.

This invention relates to improvements in vcushion tires for vehiclewheels and more particularly adapted for automobile uset lt is oneoft-he objects of this invention to provide a cushion tire which issimple' in construction, eliicient and durable in use and 'in which allof the desirable features of a pneumatic tire are present.

A further object of this invention is to'y provide a cushion tire withmeans for yield- 'ingly holding the easing jof the tire in expandedposition and to prevent the Idepres- -sion of the casing beyond acertain extent.

A' further object of the invention is to provide a cushion tire with`nieans for distributing or equalizing the' strain to` all parts of themeans for holdingl the tire in ex'- panded position when' a portiony ofthe tire is depressed.

A- further object of the, invention is to provide a cushion tirel withmeans for securely and removablyy fastening the casing. and otherFlexible portions of ,the tire to the rim so that parts may, be easily.replaced when desired.

With the above, and'other objects in View, the invention consists of thecushion tire and its partsand combinations as vset forth in the claim,and all equivalents lthereof..

In the accompanying drawing in which the same reference charactersindicate thel same parts in all of the views: Figure 1`isa crosssectional view of the in'nproved cushion tire taken on line 1%-1 of Fig.2;

Fig.' 2 is a side elevation of a portion of the tire, parts broken awayandother parts in sect1on; and Fig. 31s a longitudinal sec- '.itional.view thereof taken on line/3 3 of Fig. l with parts removed and otherparts in section.

Referring to the drawing the numeral 5 indicates the wheel felly and 6the rim fastened thereto in any 4Well. known manner. A tire holder 7 inthe form of aband of aluminum or other metal having concave side edges Sand a peripheral groove 9 with a medial circumferential projectionclosely lits the periphery of the rim G and 1 is adaptedto have the tirefastened thereto.. A series of resilient bands 11 of a diametei`- equalto the bore oi' the tire are placed-on the 'periphery of the projection10 and fas. tened thereto by bolts 1Q whichv` pass between theoverlapping edges 13 of said bands.v 'These bands increase in widthradially outwardly so' thatthe edges oit' 'ad- Jacent' bands closelyabuteach .other and forni substantially a yielding continruuls tubularband,extending around the projection 10; Mounted within each band is aresilient spring 14 and within the resilient spring is a core. springBoth cf these springs vhave overlapping end portions which Aare oil'-set with relation to each other, and the ends of the springs adjacent tothe bands are also oil'set ith-.relation to the edges of the bands andare held in the same manner by the bolt-12. The resilient springs arebent to forni side 'loops 16 and a medial loop 17 wl1ich bears againstthe inner circum-ference of the band 11 at apoint dia- I'netricailyopposite the. ends of said band and is adapted to yieldingly .reinforcethe band at this point and to take up or absorb vibration. Each corespring is also proL vided with sidev loops 18 'and a inedial'lo'op 19and these loops extend within the" corresponding 'loops of the resilientsprin's 14 ashort dist-ance'with the return bends 2O of the loops of theresilient 'springs engaging'thereturn bends 21 of the loopsof the coresprings. The screws 12 also hold U shaped stop -member-s 22 .within thecore springs and the end portions 23 of these members are bentout-Wardly'tc a position to bein-the path of movement of the returnloops 21 When the-tir" `vis undulyv depressed or flattened to limit`liid depressionV The medial' loops of the resilient springs thereto.will be forced inwardly by its engagement with the medial loops and theStrain will be transmitted to all oi" the other 'spring members andequalized.

l The spring members arecovered and-protected by meansof an innerand anouter tubular casing 26 and 27 respectively which are removably fastenedto the rim. The inner casing is formed ofvfelt, rubber or other,

material andthe side edge portions thereof rest in the peripheralgroove9 of .the tire holder with the `side edges butt'ing againstthesides of the annular projection 10. The

'outer casing27 is lformed of canvas, rubber or other ,desirablematerial and extendsl around't-he 'linner` casing and its side edgeportions lap lover the concave side edges 8 of the tire holder.Annular'clamp'ing rings 28 having-convened sidefaces 29 have theirvconvexed faces bearing againstthe opposite side edge portionshof theouter casmg and thevsaid casing 1s tightly clamped between said ringsand thel tire -holder by means ofl bolts 30 which extend through the.holding member, the casing,-the clamping'rings and through -side plates31.

The side platesI extend beyond the inner periphery ofthe tire holder andengage the side edges of the rim 6 to prevent lateral movement of theholder on said rim. The inner periphery of. the t-ire holder is providedwith a g''ove 32 'to accommodate the nuts of. the bolts 12.

From the foregoing description vit will, be seen that a cushion tire isprovided which has all the desirable attributes ofthe pneumatic tire andis strongand durable and may be easily repaired.

What .We claim as our invention is:

vided with concave side portions and a peripheral groove and having amdal circumferential projectioma series of' resilient .bands connectedtotheprojection, resilient members positioned Within the bands andprovided with side loops 'andmedial loops A cushion tire, comprising aholder pro- 'A35 and with return bends, the medial `loops bearingagainst the inner v valls'of the hands, resilient co're memberspositioned withinv the resilient members and provided'with loops and"return bends, the'return bends of both members engaging each other,Vstop lmemf, bers carried by the holder which are posi? tioned to beengagedby -the return bendsof'. the core members, an inner casingcovering the bands andthe members and having its holders, andbolts'clalnping said' clamping rings 4to the holder.

In vtestimony whereof,

We affix o ur signal tures, in 'presence of two Witnesses.
